Menelaus and Paris
The duel between Menelaus and Paris in The Iliad is famous, but later, according to one tradition, Menelaus gets hold of Paris's body after he's shot and killed by Philoktetes' poisoned arrow, and inflicts abuse upon it. As I understood the legend, Paris died a lingering death inside Troy after his discarded first wife Oenone refused to heal him. How did Menelaus get hold of the corpse to desecrate it?
Yes, this detail is important.
